Etoblattina sp. 
The wings of this species have a brownish color as pre- 
served. The subcosta has two or three simple branches be- 
yond the end of the costa. The radius is united with the sub- 
costa at the base, and reaches almost to the apex of the wing. 
Its three or four branches are oblique and forked. The media 
gives off branches early and fills the apex of the wing. At the 
base it runs close to and apparently unites with the radius. 
A considerable interspace is seen between the media and 
cubitus. This area is elongate, broadest in the middle, par- 
tially closed at the basal and apical ends. The cubitus is a 
strong vein, and reaches well onto the apical border. Its five 
or six branches are very oblique, simple or once forked. The 
anal area of this species is unknown. It is probable, from the 
shape of that part of the wing preserved and from its resem- 
blance to the species described above, that the wing has an 
ovate form with moderately expanded anal area. Length of 
wing, 17 or 18 mm.; breadth, 9 or 10 mm. 
This species, as well as the one last described, can with little 
hesitation be referred to the genus Htoblattina. The brown 
color, as well as the size of the wing’, suggest a possible con- 
nection with EF’. fulva described above.

Etoblattina sp.? Pl. LXXX, fig. 4. 
The hind wing shown in photograph, figure 4, plate LX XX, 
is probably of the genus Htoblattina, although it is light-col- 
ored, in which respect it suggests the genus Spiloblattina. 
The radius is strong, branches early, its divisions reaching 
almost to the apex. The median area is slender, branches first 
opposite the second branch of the radius, its divisions run- 
ning to the inner border. At the base it runs close to and 
probably unites with the radius. The cubitus is a strong vein. 
Its four or five lower branches are oblique and parallel. The 
first anal vein is deeply impressed and strong to the base. The 
area beyond the first anal is unknown.
